Description

Gas safety management system using adaptive distributed objects

The present invention relates to a gas safety management system, and more specifically, by organically fusing the detection data of each of a terminal carried and carried by a worker and a detection device installed at a work site, the safety of the worker as well as the safety of the adjacent worker It relates to a gas safety management system using an adaptive distributed object that promotes safety simultaneously, and furthermore, the propagation of an emergency situation is implemented immediately and subsequent activities such as relief measures can be more promptly induced.

Since most of the working environments such as gas pipelines, oil storage tanks, and tanks installed in the basement as well as factory facilities are closed environments that are blocked from the outside, residual gas remains in the internal space or work such as repair, replacement, or maintenance is in progress. It can be said that there is a high possibility that a fatal safety accident will occur if the gas is leaked during the period.

These safety accidents can be said to be fatal enough to affect the lives of workers, but their occurrence is continuously repeated due to human factors such as insensitivity to safety, lack of awareness, and work performance by unqualified persons.

On the other hand, in the case of a gas with chemical properties such as colorless and odorless, the operator cannot recognize it with his or her own senses, so it is important to apply an infrastructure using a device that precisely measures the presence or absence of a specific gas, its concentration, etc. Furthermore, it can be said that effective relief and prevention of fatal gas accidents are possible even when exposed to trace amounts only when emergency situations are quickly shared and spread.

However, in the case of the conventional work environment, the method that relies only on the gas detector possessed by the operator is mainly applied, so in an environment where the surrounding noise is large or the operator's field of vision is blurred, the operator may not recognize the danger signal of the gas detector at any time. can

In addition, in the conventional case, since the gas detector is only individualized for each individual worker, even if there is some usefulness in individual relief, information on gas leakage is not immediately shared with surrounding workers, so it is necessary to prevent the overall safety accident of the group of workers. It can be said that there are intrinsic limitations.

The present invention was devised to solve the above-mentioned problems in the background as described above, and combinedly applied gas-related data generated from a detection device fixedly installed in a work environment as well as a terminal device carried or carried by an operator. By doing this, it is possible to detect the gas leak environment more accurately and precisely, as well as sharing the detection data generated by the terminal each worker carries with workers located in the adjacent area in real time, thereby promoting the safety of the entire worker more effectively. It aims to provide a gas safety management system using an adaptive distributed object that enables relief activities to be implemented more immediately.
